High Strength Carbon Steel Adjustable Rebar Coupler

Adjustable Rebar Coupler is a versatile connecting component with adjustable length or position, widely used in construction, machinery and assembly.When the bars cannot be brought butt to butt (as it happens often in cages manufacturing), Caging splices are the answer. Both bars are threaded with a standard  thread, and a “Caging Assembly Set” is used to connect them. This set is constituted of 3 pieces preassembled together: a caging stud, a long bridging coupler and a lock-nut. The end of the caging stud bears a female thread that fits on one bar (Preferably the top bar in case of vertical cages). To connect the two bars, the bridging coupler is unscrewed from its stud and is screwed onto the second bar. Gaps between the two bar ends can be bridged by this system.If one of the bars is concreted beforeassembly of the reinforcement, its thread must be protected by a pocket former.When the bars cannot be brought butt to butt (as it happens often in cages manufacturing),  Caging splices are the answer.

Size: from 12mm to 40mm.

Meet the requirements of steel bars: HRB500/B500B/SD600/ASTM 75

Material: 45C/40CR

▎Advantage:

• Flexible adjustment for length, position and installation tolerance.

• Wide adaptability to different working conditions and structures.

• Stable connection, high strength and reliable performance.

• Easy to install and adjust, improving construction efficiency.

• Cost-effective, reduces the need for multiple fixed-size components.

▎Application & Installation Position

• PC structures, installation of prefabricated columns, walls and beams, eliminating prefabrication errors and on-site installation deviations.

• Reinforcing bars fixed at both ends and unable to rotate, such as through-length bars of beams, beam-column joints, and closed frames.

• Remedies for insufficient or excessive reinforcing bar lengths due to construction errors or incorrect cutting, adjusted directly on-site.

• Parts requiring precise positioning and controllable lengths in bridges, cap beams, pier columns, and municipal projects.

• Reinforcement, renovation, and extension of reinforcing bars in old buildings.

▎FAQ

Q1: What is an adjustable rebar coupler?

A: It is a left-right thread LR type rebar coupler, used to adjust rebar spacing without cutting rebars on site.

Q2: How does the adjustable structure work?

A: One end is left thread and the other is right thread. Rotate the coupler body to pull two rebars closer or apart freely.

Q3: Does adjustable coupler reach equal-strength standard? A: Yes. It meets ISO 15835 and seismic codes, tensile strength exceeds base rebar.

Q4: Can it be used for seismic building projects? A: Absolutely. Our adjustable coupler passes anti-seismic fatigue tests for high-rise and bridge construction.
